Here, because of the condition \(s_k(0)=0\) , the “off” node will move as \(\mu _1\)  is varied. Figure REF  considers the integrable version of Figs. 4 and 5 (the only ones for which \(\det J<0\) ) in [1]}. The parameters specified by the authors are \(j_{11}=12\) , \(j_{12}=4\) , \(j_{21}=13\) , \(j_{22}=11\) , \(\beta _1=1.2\) , \(i_1^0=2.8\) , \(\beta _2=1\) , \(i_2^0=4\) , \(\mu _2=0\) . The values of \(\tau _1\)  and \(\tau _2\)  (as well as \(\nu _1\)  and \(\nu _2\) , not specified by the authors) have been chosen as 1 throughout This has the additional advantage that the flow is purely dissipative, facilitating dynamical conclusions from the landscape..
